摘要：

The main direction of hydrogenative ring-opening of propylcyclobutane on Pt/SiO2 catalyst in the temperature interval of 373-673 K is the formation of n-heptane through cleavage of the sterically hindered C1-C2 bond. The unusual selectivity can be attributed to adsorption of both the ring and the propyl group on the catalyst. With increasing temperature, the selectivity of ring-opening approaches the statistically expected ratio.
